| 摘 要： | 随着矿井开采深度增加,软岩巷道变形加快,维修费用增加,制约着矿井的高产高效生产。结合某矿1203工作面运输顺槽底板瓦斯抽排巷地质条件,对深井软岩巷道顶板深部围岩矿压进行了观测,观测内容包括深部围岩位移和分区破坏情况。在对实测数据分析的基础之上,得出巷道顶板深部围岩位移演化规律和分区破坏规律。通过对观测成果进行分析,提出了巷道掘进和支护对策,要求改变现有的巷道支护方案并提高施工队伍素质与水平。

| Abstract: | With the increase of mining depth,the deformation of soft rock roadway is becoming serious,leads to a high cost of maintenance and restrains the mine's high production and high efficiency.Based on the geological conditions of gas extraction roadway in the floor of haulage gate of 1203 working face in one coal mine,the deep roof strata pressure of deep soft rock roadway was observed.The observation contents include displacement and failure the zone of deep surrounding rock.Through analyzing raw data suggests... |
